It's illegal for a white light to be pointed rearward like that. But I'm sure
the rider felt that it was so dangerous to ride a bike that she should
violate that law, and also blind or inconvenience any other road users.

The safest course of action for a ton and a half of moving metal is to
blind it so it can't see where it's going. Well, tbh, the long term
safest thing...
